stonetree Posted March 10, 2011 Report Share Posted March 10, 2011 Car runs great then next time I start it, it runs too rich. Shut it off then restart it runs either better or great. Shut it off and I never know how its going to run next time I turn the key. Fuel pressure rmains the same. Could it be the MAF or injectors? It seems like a switch is being thrown.

AlexNYC Posted March 10, 2011 Report Share Posted March 10, 2011 Stonethey tell you, need the car detail. But you are starting at the two obvious location, maf and injectors. Link to comment Share on other sites More sharing options...
Komeuppance Posted March 10, 2011 Report Share Posted March 10, 2011 Take a look at this:http://www.starquestclub.com/forum/index.php?showtopic=116976TPS/ISC reset, CTS, MAP sensor/solenoid. Can you give more detail on the temperatures the engine is at when it's running well/not so well?? -Robert Link to comment Share on other sites More sharing options...
The Rabbit1 Posted March 10, 2011 Report Share Posted March 10, 2011 when it runs better does it have a sputter or stumble at idle? where does it idle at? Link to comment Share on other sites More sharing options...
stonetree Posted March 11, 2011 Author Report Share Posted March 11, 2011 It does it when the engine is cold or hot and at any rpm. Link to comment Share on other sites More sharing options...
MikeMeyerhoff Posted March 11, 2011 Report Share Posted March 11, 2011 Is the MAP sensor on the firewall working properly? Check the vacuum lines going into the solenoid to make sure they are hooked up correctly. Link to comment Share on other sites More sharing options...
stonetree Posted March 11, 2011 Author Report Share Posted March 11, 2011 Thanks for all the great help. The problem is fixed. I sold it to a mechanic, who has been wanting one for a long time. So it has a good home. Link to comment Share on other sites More sharing options...
Indiana Posted March 11, 2011 Report Share Posted March 11, 2011 Those loose dirty injector clips are killer. Link to comment Share on other sites More sharing options...
